The Moon that Embraces the Sun(해를 품은 달)

Set in the Joseon dynasty, two brothers find themselves falling in love with a female shaman, who does not remember her noble past. Lee Hwon is the Crown Prince, but he finds the role a burden to bear. He would rather have his older, more talented brother Yang Myung play the role, but because Yang Myung is an illegitimate child he has no right to the crown. When Lee Hwon tries to escape the palace walls for a little adventure, he encounters Heo Yeon Woo, the intelligent daughter of a nobleman. It's love at first sight for him, but Lee Hwon is also set to marry another nobleman's daughter, Bo Kyung. Little does Hwon realize, but Yang Myung is also falling for Yeon Woo.
